Sample Question Videos

Worksheet • 9 Questions • 1 Video

Q1:

One or more of the following types of electromagnetic radiation contain at least some wavelengths that are ionizing. Which of these types can or must be ionizing?

  1. Ultraviolet
  2. Infrared
  3. Microwaves
  4. X-rays
  • Aa and d

Q2:

The more strongly electromagnetic radiation interacts with living tissues, the more damage it can do to those tissues. Further inside the body of organisms are more vital organs and tissues, damage to which is more harmful to organisms. The strength of interaction with human body tissues and the depth of penetration into the human body of different types of electromagnetic radiation is shown in the diagram.
